.. _-onCompleteWithBreaker-: onCompleteWithBreaker ===================== Signature --------- .. includecode2:: /../../akka-http/src/main/scala/akka/http/scaladsl/server/directives/FutureDirectives.scala :snippet: onCompleteWithBreaker Description ----------- Evaluates its parameter of type ``Future[T]`` protecting it with the specified ``CircuitBreaker``. Refer to :ref:`Akka Circuit Breaker` for a detailed description of this pattern. If the ``CircuitBreaker`` is open, the request is rejected with a ``CircuitBreakerOpenRejection``. Note that in this case the request's entity databytes stream is cancelled, and the connection is closed as a consequence. Otherwise, the same behaviour provided by :ref:`-onComplete-` is to be expected.
